Bathtub bladder 375 L
A big plastic liner that sits in your tub and fills from the tap. 375 L for about $60, the cheapest per litre by far.
The catch: you need warning. Fill it when the storm is forecast, not after the taps stop.
It's single use, so treat it as your first-week supply, not long-term storage.

What I like
- Cheapest storage per litre by a wide margin.
- Packs into a drawer. Takes no space until you need it.
- Keeps the water covered and clean, unlike filling an open tub.
- Hand siphon pump makes it easy to fill pots and jugs.
What I don't like
- Only works if you get warning and fill it before the taps stop.
- Single use. Most aren't designed to be emptied, dried and reused.
- Ties up your bathtub while it's full.
- The pump is basic and slow, and some owners find it fiddly.
Things to consider
- Keep it in the bathroom with a note, so anyone at home can set it up when a storm is forecast.
- Clean the tub well before laying it in. Tiny cuts from sharp edges can cause leaks.
- Use the water within about 2 weeks. Treat it before drinking if it's been longer.
- Pair it with jugs or bottles. It's a first-week supply, not long-term storage.
BEST FOR
Anyone in an area with forecast storms (ice, hurricanes) who wants a lot of water for little money.
